Pest Management (PM) for Papaya
Introduction
Papaya cultivation faces challenges from various pests, including insects, mites, and nematodes. Integrated Pest Management (IPM) is essential for maintaining healthy crops and ensuring high yields. Here are the main points for managing key pests in papaya provided by Khethari Agri Tech Private Limited.

Conclusion
Effective pest management in papaya cultivation provided by Khethari Agri Tech Private Limited ensures healthy crop yield and quality. Integrated Pest Management (IPM) strategies, which combine biological, cultural, mechanical, and chemical methods, have proven to be the most sustainable and environmentally friendly approach. Regular monitoring and early detection of pests, such as the papaya mealybug and fruit fly, are crucial to prevent infestations from becoming severe. Employing natural predators and biopesticides can reduce reliance on chemical pesticides, minimizing harmful residues and preserving beneficial insect populations. Ultimately, a well-implemented IPM program enhances papaya production while promoting ecological balance and long-term agricultural sustainability.
